Title: Manufacture of crystal substrate
Inventor: SAKAI SHIRO
IPC: H01L21/20
Filed: 1991-04-18
Abstract: PURPOSE:To obtain a second crystal substrate of low transistor density and little distortional stress which decreases dislocations that block actions of a semiconductor device and distortional stress that proliferates and propagates it to obtain favorable actions of the semiconductor device in the case of overlaying a first crystal substrate with a second crystal substrate having a lattice constant and a coefficient of thermal expansion different from that of the first crystal substrate and in the case of forming semiconductor devices such as laser diodes on the second crystal substrate. CONSTITUTION:An Si substrate 1 is overlaid with a GaAs epitaxial layer 3 via a selective etching layer 2. Next, an etching groove 4 is formed extending from the GaAs epitaxial layer 3 to the selective etching layer 2, and the latter layer is partially etched away by utilizing the groove 4 in consideration of such a special shape that a large distortional stress is developed in the GaAs epitaxial layer 3. Thereafter, dislocations are decreased by thermal annealing on the GaAs epitaxial layer 3, and a distortional stress is relaxed by etching away a part of the GaAs epitaxial layer 3, so that a GaAs epitaxial layer of low dislocation density and little distortional stress is obtained.

Abstract: PURPOSE:To improve the quality of recording picture as much as possible without decreasing recording speed by providing a third recording control means updating the time length of voltage application at every line in response to the discrete value of a counter and setting time length so that the recording time of each line is equalized approximately. CONSTITUTION:A counter 10 counts the number of picture data blocks discriminated as no containing of black picture element information.

An arithmetic section 11 computes the recording time length of the picture data blocks, the time length of the application of recording voltage, so that the recording time of each line is equalized approximately by arithmetic processing based on the discrete value of the counter 10. A third recording control section 12 controls the recording time of the picture data blocks, and updates and controls the recording time length of the picture data blocks to recording time length computed by the arithmetic section 11 at every line.
